Abstract
The purpose of the study is development of a heat flux sensor for measuring heat flux from burnt gas to engine inner wall to improve thermal efficiency of the engine in SIP innovative combustion technology project. The heat flux measurement method, where heat flux is derived through transient heat conduction analysis combining with surface temperature measured with MEMS thin film resistor sensor, was experimentally examined. Heat flux measurement experiment in a butane-air premixed combustion system in a open chamber with the MEMS sensor was conducted. It was confirmed that the sensor and the method can measure 100kW/m^2 level heat flux at 1ms level temporal resolution.
